CHARLES E. SCHNEBELIN, OE PEORIA, ILLINOIS, l-QSSIGNOR TO STUBER 8n KUGK 00.,

' or rnonra, ILLINoIs, A oonroas'rroiv or ILLINOIS" MEANS T SECURE MACHINE ELEMENTS TO ONE ANOTHER.

application filed December 31, 1920. Serial H0. 434,359.

T 0 al Z to 710m it may concern it known that 1, CHARLES F. SCHNEB-' ELIN, a citizen of th United States, residing at 653 Stanley Ave, Peoria, i the county of fi Peoria and State of Illinois, have invented certain new and useful Improvements in Means to Secure Machine Elements to One Another; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to a new means of rigidly connecting two membersof a driving element, pertaining particularly to a new and novel arrangement for securely attaching the beater driving wheel of an egg-beater to its driving shaft orcrank.

The purpose of my invention isto so construct the two parts of a device of the nature described that a permanent connection is the result, together with the elimination of all chance of looseness or relativement movement of the parts becoming apparent.

Particularly in an egg-beater structure, the means heretofore employed for attaching the crank shaft to the driving wheel have not been effective in the matter of creating a positive connection free of looseness and of all chance of the parts finally becoming so loose as to lose their operative relation entirely, and with th above purpose in view, I have designed the form of connection now to be described, aided by the accompanying drawing wherein,

Figure 1 is a side elevation of part of an egg beater wherein my invention is shown.

Figure 2 is an elevation of the same as seen from another angle.

Figure 3 is a sectional elevation of part of the beater-driving wheel, viewed in the same direction as Figure 2, and prod ced on a much larger scale, the driving shaft or crank shaft being shown in connection therewith.

1 indicates portions of a two-part main frame and the handle portion of an egg beater of a conventional type, 2 is the wheel for driving the beater 3 by means of pinions 4t, and 5 is the crank-shaft for driving the said wheel.

My invention consists in bending or recurving the shaft 5 upon itself at a point between its ends. or more properly, between those portions that have their support in together they form a wheel havingspaced,

flanges t perforatedto engage the described spaced pmions i, this being common practice, however.

Said, sections are oppositely indented to form the depressions 8 for receiving the arm .6 nto them as clearly shown in Figure 3,

the sections, when abutted, enclosing the arm, the abutting surfaces lying preferably in the same plane with the abutting surfaces of the. recurved arm extensions.

The wheel sections thus formed appear ontheir outer s urfaces as in Figure 1 where, of course, bntoneof the sections is shown.

heew 6 n be l a at y m nt with reference-to the operating handle or knob of the shaft, it having been shown in but one position directly in line with and opposite the said handleor knob.

The wheel 2 need not be made of two sections in the form shown, of course, in order to enclose the arm, but may be made in other ways and still enclose the arm 6 in as firm a manner as that shown, and various changes may be made without departing from the spirit and intent of the invention and Without departing from the scope of the accompanying claims.

I claim:

1. A shaft having an integral laterally extending arm, and an element for rig/l connection with said shaft including two parts clamped together on opposite sides of said arm.

2. A member adapted for rotation bent upon itself into a lateral projection, and a member lying adjacent the projection having a part conforming to, overlying, and en closing said projection and securing both members in rigid relation.

3. A shaft bent or recurved upon itself forming a projection, and a member lying adjacent the projection having a part conforming to the same and enclosing it, securing said members in rigid connected rela tion.

4. A shaft bent or recurved upon itself at a point between its ends forming a lateral extension, and a member mounted on the shaft adjacent the projection, the same having a part formed to enclose the said projection for holding the members in rigid connected relation.

5. A shaft bent or recurved upon itself forming a lateral projection, and two members mounted on said shaft, one of the members having a depression to receive the projection into it, said members enclosing and securing the two members in rigidrelat-ion.

6. A shaft bent or recurved upon itself forming a laterally extending arm, a member mounted on the shaft at each side of the arm and each having a depression corresponding to substantially one-half of the arm, and means to clamp said members upon the arm.

7. A shaft bent or recurved upon itself between its ends forming a laterally extending arm, a member to be driven by said arm comprising two parts mounted on the shaft, one at each side of the arm, each having a depression therein opposite the arm together adapted to enclose the arm, and means to secure the parts together on the arm.

8. An egg beater including in its-construction, a shaft, a frame including spaced bearings for the shaft, said shaft being reourved or bent upon itself to form a later- 30 ally extending arm between said bearings,

with said arm to be driven thereby, said member being fashioned to receive a portion of the arm into it, and means to secure the member and arm in rigid relation.

10. An egg beater including in its construction a shaft, a frame including spaced bearings for the shaft, said shaft having a laterally extending arm between said bearings, and a wheel mounted on said shaft comprising a part at each side of the arm, each portion having a depression conform ing substantially to the form of the arm adapted to enclose the same, and means for securing the parts of the wheel together.

In testimony whereof I affix my signature in presence of two witnesses.
